SOAP-PULVERIZING MACHINE.

SPECIFICATION forming part of Letters Patent No. 784,767, dated March. 14, 1905.

Application iiled August 27, 1901. Renewed August 15, 1904. Serial No. 220,708.

To if/ZZ whom, it Netty concern:

Be it known that l, RICHARD H. L. TALcor'r,

. a citizen of the United States of America, and

a resident of Brookline, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Soap-Pulverizing Machines, of which the following is a full, clear, and exact description.

This invention relates to machine for pulverizing soap or making' soap-Hour, as the product is sometimes termed.

The object of the invention is to provide an improved and simplified machine for the working up of a plurality of bars of soap into a comminuted condition, the soap-iiouras thus produced being adaptable especially for the washing of fine woolen fabrics and laces.

The machine as contemplated under this invention comprises in the composition thereof a suitable frame or supporting structure, a rotatable and preferably power-driven gauze por screen covered or otherwise foraminous or suitable abrading-cylinder for exerting a comminuting or pulverizing action upon the bars of soap, a support adjacent the cylinder for the bars of soap, means for the constraint and guidance of the soap-bars as they are gradually fed forwardly to remain subject to the abrasive and coinminu'ting action ofthe cylinder, and a follower for exerting a proper degree of pressure against the soap bars to constantly maintain them in position to be ground away by the cylinder;l and the invention, furthermore, comprises a receptacle for the reception of the soap-flour and a casing or cover for suitably inclosing the cylinder, whereby that proportion of the powdered soap which is carried more or less around with the cylinder and liually is thrown therefrom centrifugally may be restrained against being' scattered, so that it will settle down into the receptacle for the fiour.

The invention, furthermore, comprises in a machine for the purpose stated, characterized as above, means for insuring automatically the cessation of the impelling force against the follower at approximately the time when the bars are almost completely reduced, so that vthe follower will not itself be brought against the cylinder to injuriously act thereon or to be injuriously acted upon thereby.

The invention also comprises details of constructions and particular combinations of parts, all substantially as hereinafter described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, in which my present improved machine is fully and clearly illustrated, and in which` Figure l is a side elevation, the inclosing casing for -the cylinder being indicated as swung rearwardly open. 2 is a plan view of the machine with parts of the double screencovering for the cylinder broken away to illustrate the construction of the screen-supporting part of the cylinder. Fig. 3 is au end elevation of Fig. 1. vertical cross-sectional view of the machine with the screen-inclosing casing in its closed position.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents the frame and supporting' structure of the machine, having suitable standards or uprights provided with the bearings a for the d riving-shaft lion which is mounted the abrading-cylinder C for the reduction of the soap bars af, and said shaft has thereon the driving-pullcy D. The cylinder ranges horizontally and axially longitudinally of the machine and, as shown, has for the supporting structure thereof a plurality of disks?) I), understood as centrally circularly apertured and fitted on the shaft and held in separation by the intermediate disks c c of smaller diameter.

Directly overlying the disks b is a screen wi or analogous opon-work structure, haring interstices comparatively wide, the same being secured in any suitable manner, and on this suitably-continuous support is placed the overlying covering, which is most advantageously composed of comparatively fine wire-gauze z/ and is preferably made with the warp-wiresthose which run longitudinally of the cyling derformeld with squared or otherwise sharp edges for increasing efficiency in the abrading action on the soap bars.

Fig. 4. is a partial Located at the front of the cylinder is a l the flour into the receptacle, especially beshelf-like support or table E, on which the bars of soap rest and are horizontally slid or gradually fed thereover for endwise presentation against the abrading-periphery of the cylinder.

F represents a follower, here shown as consisting of a wooden bar resting on the soapsupport, ranging longitudinally parallel with the cylinder-axis and adapted to bear againstI the outer end of the several bars of soap, which are shown as separated from ea'ch other and held not only in their separation, but also against rising' by the rack-frame G, which has one end thereof hinged to an upright (l, extending above the level of the soap-support, said rack-frame comprising, in addition to the longitudinal bai-sf, one or more, to rest against or to have positions adjacent the tops of the soap bars, the transverse bars g, between the several of which the soap bars are disposed. The follower, which is free for a horizontal transverse niotion, has the soap crowding pressure imparted thereto by the stress of the sheave-guided cord or'cords t, one end of each of which is attached to the follower, while at its depending end is a suitably heavy weight if. The table and the rack-frame G may be regarded as a carrier or feed-receptacle and as a matter of expediency may be removable from the machine without interference with or interference by the follower, so that a removed carrier could be loaded while another was in use in the machine.

H represents a `shelf onto which the weights may be lifted to rest, leaving the cords slack when the machine was not in use, so that the follower F may be drawn forwardly beyond the table E onto the portion of the framing j to enable the removal of the table and rack to be loaded with bars or blocks of soap and the replacement thereof by another loaded earrier.

Hinged to the framing at the rear of the cylinder is a casing J for inclosing' the cylinder when the machine is in operation and for preventing that proportion of the powdered soap which does not pass directly from the soap-bars, from which it is worked off into pulverized condition down into the receptacle M below the cylinder, but which is carried partially or completely around with the cylinder and finally centrifugally thrown therefrom, from being scattered. rIhe aforesaid receptacle M beneath the cylinder may be drawn endwise of the machine outwardly suf-n ficiently far to enable one to remove the soapiiour therefrom.

m mf, Figs. 2 and et, indicate rods for the support of grating o and plate fa, the latter to prevent the remnants of soap at about the end of the soap reducing operation from mingling with the soap-fioul' in the receptacle, while the grate facilitates the passage of tween thesoap bars, whereat the soap -bar support E may be suitably apertured, and in order that the follower may not be crowded toward the cylinder in the soap-reducing operation at the iinal stage when only small seginents of the soap-blocks remain a shelf or other limiting appliance, as indicated at N, is provided suitably below the weights The rest N, which is shown as being adjustable and having its position properly to intercept the descent of the weights in proper time, insures a termination of the stress by the follower toward or against the cylinder.

The purposes and capabilities of the devices and incidentally their manner of operation having' been explained in conjunction with the speciiication of the parts and devices, further description of the operation and mode of utilization of the machine is deemed superiiuous.

I may advantageously make the outer covering or the support therefor which is mounted on the disks, or both, sectional, so that in case portions thereof become broken or worn out they may be replaced readily and at small expense.

By the employment for the abrading-surface of the cylinder of the covering of gauze, having one set of the woven wires thereof arranged longitudinally of the cylinder and the other set at right angles thereto and in planes perpendicular to the axis of the cylinder, I am enabled to produce the iour of soap which as to the nature or formation of the particles is of great uniformity and of a character susceptible of becoming' readily dissolved in use. This will be explained as follows: In the action of the cylinder against the soap bars the longitudinal wires of the gauze exert an action for producing thin shavings more or less curled and feathery, and the round running wires of the gauze operate to cut the shavings into even particles. Were a cylinder having' a grating-surface employed, there would be a great diversity in the size of the particles, as well as a greater solidity of many of the particles, and the failure to derive a product as desirable and acceptable as that of this machine.

Having thus described my invention, what I claim, and desire to secure by Letters Pat-A ent, is-

1. In a machine :for pulverizing a plurality of bars of soap, in combination, a rotaryV abrading-cylinder, an adjacent soap-bar support, a frame or rack having' upper longitudinal bars to constrain the soap bars from rising, and having transverse bars to extend between and hold the soap bars separated, a follower resting on the support behind the soap bars, and means for imparting an impelling' force to the follower.
